A SFP (Small Form-Factor Pluggable) transceiver is a compact, hot-swappable device that can be used for both transmit and receive data and also plugs into a physical port of a network device. It is used in the communication network and has a transmitting side and receiving side. The SFP transceiver has a laser which communicates with the receiving side of the other optic on the other side. SFP transceivers are designed to support several communication standards including SONET, Gigabit Ethernet and Fibre Channel, and their interfaces on a networking device such as a router provides a modular device that can be freely adjusted to fiber optic and copper networking specifications.
Undoubtedly, the effectiveness of data centers depends on their uptime. A layer of better visual management can dramatically reduce the possibility of human errors. Human errors and malpractices are a no-no as these things can lead to money-wasting downtime though cables come with factory printed legends. However, these legends are tough to locate…. Let us talk about how color coding is better than other cable management technique?
Data Center Dude explains the differences between multimode fiber types and which to use over what distances.
Learn Fiber Optic technology basics including fiber types, connector types, types of impairments, and best practices for installing, certifying, and troubleshooting fiber optic systems. Sessions will include technology overviews, reviews of test applications, and in-depth product demonstrations.
While once cost prohibitive, 100G network upgrades are now a viable option to improve network performance. The emergence of the QSFP form factor has brought economies of scale to 100G upgrades, putting 100G within the cost reach of both small and hyper-scale data center operators. With a small profile and reduced power consumption, the QSFP form factor is the choice of switch manufacturers for 100G platforms.
The Internet of Things (IoT) is at the beginning of its golden age. Forecasts note that the number of connected devices could exceed the 20-billion mark by next year and could reach 50 billion by 2022. For all this, we are basically using just one network protocol. The still-dominant IPv4 standard uses 32-bit addresses, only making around 232, or 4.3 billion different addresses possible. Luckily, a new 128-bit format has existed in principle since 1998. This IPv6 standard offers an address space of 2128, or around 340 sextillions, eliminating any concerns. However, DE-CIX measurements show that currently, only around 5 percent of traffic corresponds to the new standard.
400ZR pluggable coherent transceivers for up to 80-120km distance will emerge in 2020~2021 time frame, and their cost is expected to be comparable to today’s 80km 100G pluggable PAM4 transceivers, which results in essentially 3~4x cost per bit reduction.
The more data center managers know about extending the life of their equipment and infrastructure, the better prepared they’ll be to influence the procurement process and take advantage of funds that do become available. Two tactics to consider are: Dark fiber. Many ISPs installed more fiber than was initially needed and dark fiber can be activated and leased; and extend the life of existing fiber optic connections by upgrading termination equipment.
Fluke Networks, Hirose and Harting have released an adapter supporting the ix Industrial connector for Fluke’s DSX CableAnalyzer family of network cabling certification tools. The ix Industrial is a rugged Ethernet connector for harsh environments, based on IEC 61076-3-124 standard with a 70% smaller size than the traditional 8-pin modular (“RJ-45”) connector. The new adapter allows the DSX Series to connect to cabling systems employing the ix Industrial connector for the purposes of pre-startup verification and troubleshooting.
The TIA-942 standard for data centers is the world’s most popular data center standard. It’s used by well over 70% of facilities around the world. Data center stakeholders have been very concerned about ensuring that their data center was designed, built, and approved as having met that criteria.The new TIA program ensures consistency and conformity across the audits of data centers, which will result in better performance.
